LEX1542 series

  • LEX1542-02 RJ45 to 2km MMF(SC
  • MC LEX1542-15 RJ45 to 15km SMF(SC)MC

Guaranteed operation in a wide range of temperatures from -10°C to 60°C! This product can operate stably in the severest environments.

This is a media converter exclusively for 100M, which interconverts 100BASE-FX signals by optical fiber and UTP 100BASE-TX signals.

It can be used in a wide range of temperatures from -10°C to 60°C. The product realizes miniaturization to the smallest domestic class, and exhibits high resistance to noise and reliability.

The various functions can be changed by the DIP switches, flexibly supporting construction for a wide range of carrier and stand-alone networks.
